FU RNACE-GRATE.

SPECIFICATION forming part of Letters Patent No. 367,378, dated August2, 1887.

Application Bled April 1E), 1887. Serial No. 235,365. (No model.) I

To @ZZ whom, it may concern.-

Be it known that l, CHARLES W. Eolica soN, of Creston, in the county ofUnion and State of Iowa, have invented certain new and usefulimprovements in furnace-grates, ap-

' by a system of rods and levers, or by other Mmeans,and capable ofindependent orjoint opwhich are mounted on journals c in the bars B.

The dumping-grate sections C are eXteriorly of rectangular shape, asshown in Fig. 2, and provided with fingers c, projecting inward, asshown.

D Darethe rocking-grate sections provided with journals d, which rest insuitable bearings formed in therespective dumpinggrate sections, asshown in Fig. 2. The rockinggrate sections consist, principally, of acentral bar, from which project ngers e, fitting between the fingers cof the'dumping-grate sections. It will thus be seen that the rocking anddumping grate sections have independcn movements upon their journals.

The rockinggrate sections D, shown de tached in'Figs. 3 and 4, are eachprovided withan arm, f, having a boss, f', at its lower end, throughwhich boss passes a bolt or pin, g. Each section C of the dumpinggrateis furnished with a lug, h, to which is attached by a pin, z', a link,E. To the pins g ofthe arms f of the rocking-grate sections a rod, F, isattached, which may be connected directly or through the interventionofa link with a lever,

dumping-grate are connected by a rod or rods, H, leading to the lever I.

The ashvpan is shown by K, to which one or more brackets or guides, 7c,are attached for the purpose of guiding the rod or rods H.

The operation ot' the invention will be readily understood. Vhen it isdesired to dump the fire, the sections C of the dumping grate are, bymeans of the lever I, brought to a slanting position,as shown in dottedlilies in Fig. l, it being understood that the rocking grate sections D"are also worked or dumped at the same time by means of the lever G. Whenthe fire is to be shaken, the dumpinggrate sections C may be keptstationary and the rockinggrate sections D only moved. By connecting onehalf ofthe dumping and rocking grate sectionsl with rods and levers, asshown, and the other halt with another set of rods and levers, onehalfof the `lire can be dumped and better facilities for cleaning the restof the fire obtained.

The grates may be worked by a rack-and-` In testimony whereof I havehereunto set my hand and seal.
